Microbial selection strategies that enhance the likelihood of developing commercial biological control products.

It is suggested that the reasons for such a small proportion of active laboratory antagonists having been developed into biological control products are: (1) few candidate microorganisms are tested; (2) microbes are selected based on the results of an assay that does not replicate field conditions; and (3) the amenability of microbes to commercial development is excluded as a selection criterion. Selection strategies that enhance the development of commercial biological control products are described. These include making appropriate choices regarding the pathosystem for biological control, the method of microbe isolation and the method of isolate characterization and performance evaluation. A model system of developing a biological control product active against Gibberella pulicaris, the primary causal agent of dry rot of stored potatoes, is used to illustrate the proposed selection strategy concepts. Strains with enhanced potential for commercial development were selected. This was based on th

e strain showing both favourable growth kinetics and bioefficacy when grown in commercially feasible liquid media.
